1 Figure 1. FBE coatings have been in use for underground and undersea pipeline protection for nearly forty years. Figure 2. Specially designed FBE coatings on reinforcing steel have been installed in more than 100,000 structures in the US alone. FBE PIPELINE AND REBAR CORROSION COATINGS J. Alan Kehr 3M USA Synopsis The key to a successful pipeline or rebar anti-corrosion program is the coating system. The successful coating system comprises proven high-quality coating materials and consistent, reliable application of the coating materials. Fusion-bonded epoxy (FBE) has proven to be reliable in these markets and new and improved materials are now available for specific corrosion conditions. Introduction Corrosion costs an estimated three to four percent of gross national product for direct and indirect costs in the developed countries of the world (1). Selection of the most economically effective technique for minimizing the effects of corrosion is a critical design decision. This paper will review fusion- bonded-epoxy (FBE) coating solutions for corrosion mitigation of pipeline systems, including internal, external, and 3-layer, and for reinforcing steel. The protection of pipelines, valves, fittings, and steel in concrete from corrosion is necessary to ensure long-term operation, minimize maintenance, and prevent costly service disruption, loss of life, and injury. Protective measures are extremely important; yet, they represent a small fraction of the overall cost of a pipeline system or concrete structure. Background, History, and Advantages of FBE Coating Systems A fusion-bonded epoxy is a one part, heat curable, thermosetting epoxy resin powder that utilizes heat to melt and adhere to a metal substrate. It provides a coating with excellent adhesion, a tough, smooth finish resistant to abrasion and chemicals and does not entrap solvents. FBE coatings have been used for
